FLUSHFIX® is the solution for virtually flush thread on the internal walls of a tube, or on a single metal sheet when a flush finish is necessary on the opposite side to crimping.
Because it is flush-fitting, FLUSHFIX® allows one tube to both slide and block inside another.
The FLUSHFIX® installation is completed without welding, thus eliminating the need for any reworking.
